IRS doesn't show my 2020 return

[dmcarlson48]

I filed my 2020 return via mail, because I had issues with TT efile. The payment check was processed, but the IRS doesn't show that I filed. Should I file a duplicate return?

I would wait if and until the IRS requests that you file another return. Since they processed your payment, you will not be penalized for filing a late return. They will match the payment with your return and if they determine that it is not filed, they will request that you file a new one.
