Pass parameter to another page

Within people, I own the accounts receivable table, where I am calling the page accounts receivable create, and the edit. So far, it's working perfectly. However, within accounts receivable, I have a select , where I already wanted to have selected the person I was. And also has the return list.

I needed to know how I can do, for example, by passing a parameter, whether it is being called accounts receivable or people, so in order to return, I do the treatment to know where to return.

Here is the create:

 <a asp-page="/ContaReceber/Create" class="btn btn-primary btn-sm">Criar nova Conta</a>

And here's the edit:

 <a asp-page="/ContaReceber/Edit" asp-route-id="@item.Id" class="btn btn-sm btn-success">Editar</a>

It redirects, but I need to treat it, just as I did.

This is the person ID parameter that I need to pass to the other page:

  <input type="hidden" asp-for="PessoaVM.Pessoas.Id" name="id" id="id" />

Edit: Get pass the id to the AccountReceive / Create page like this:

  <a asp-page="/ContaReceber/Create" asp-route-id="@Request.Query["id"]" class="btn btn-primary btn-sm">Criar nova Conta</a>

But I'm not sure how to deal with it here:

  public IActionResult OnGet()
    {
        ContasReceberVM = new ContasReceberViewModel
        {
            ContasReceber = new ContasReceber(),
            PessoaVM = _context.Pessoas.ToList(),
            PlanosServicos = _context.PlanosServicos.ToList()
        };
        return Page();
    }

    public IActionResult OnGet(int id)
    {
        ContasReceberVM = new ContasReceberViewModel
        {
            ContasReceber = new ContasReceber(),
            PessoaVM = _context.Pessoas.Where(m => m.Id == id).ToList(),
            PlanosServicos = _context.PlanosServicos.ToList()
        };
        return Page();
    }

It returns the following error:

Multiple handlers matched. The following matched route handlers had all the constraints satisfied:

Microsoft.AspNetCore.Mvc.IActionResult OnGet (), Microsoft.AspNetCore.Mvc.IActionResult OnGet (Int32)

asp.net-mvc asp.net-core

Instead of two actions have only one and allow the ID to be nullable and treat within it.

public IActionResult OnGet(int? id)
{
    if (id.HasValue)
    {
        ContasReceberVM = new ContasReceberViewModel
        {
            ContasReceber = new ContasReceber(),
            PessoaVM = _context.Pessoas.Where(m => m.Id == id).ToList(),
            PlanosServicos = _context.PlanosServicos.ToList()
        };
    }
    else
    {
        ContasReceberVM = new ContasReceberViewModel
        {
            ContasReceber = new ContasReceber(),
            PessoaVM = _context.Pessoas.ToList(),
            PlanosServicos = _context.PlanosServicos.ToList()
        };
    }
    string urlAnterior = Request.Headers["Referer"].ToString();

    if (urlAnterior.Contains("Pagina"))
        return RedirectToAction("");
    else
        return RedirectToAction("");
}

And in view the button may look like this:

<a asp-controller="ContaReceber" asp-action="Edit" asp-route-id="PessoaVM.Pessoas.Id" class="btn btn-sm btn-success">Editar</a>
