After you file

If you mean the IRS refund site:

 https://www.irs.gov/refunds

 

Then be sure your return  was accepted:

You can check your TurboTax filing status here:

Then  be sure you enter the first SSN on the 1040 form is  joint return and the refund amount from the 2019 1040 line 21a.

 

If it still gives an error then it is probably on the IRS end.
