Can anyone let me know what to do with tax paid by check for the previous year but still shown as tax owed in turbo tax?

I had to amend my tax return for 2019 in January 2020 and used turbo tax to amend it. However, since the electronic transfer window was already closed for TurboTax, I had to mail the amendment and check. But TurboTax 2019 still have the money I owe in the system and when I started 2020 return with information transferred from 2019, the tax I already paid by check is carried over to 2020 as the tax I owe . What do I do to eliminate this?
