Where does it show that I paid my 2019 taxes

[rjs]

I don't know what "it" is. TurboTax has no way of knowing that you paid the tax that you owed. If you paid by check or by direct debit from your bank account, your bank statement shows the payment. If you paid by credit card your credit card statement shows the payment. Or you can view your federal tax account at the following link on the IRS web site.
