You must have misunderstood.
Taxes owed can never be paid from a tax refund, federal or state, using TurboTax.
If you used the TurboTax online editions, in the File section of the program on Step 2 when taxes were owed you were given specific options on how to pay the taxes owed. Paying from a tax refund was Not one of those options.
Look at the Federal Filing Instructions page in the PDF of your tax return to see how you selected to pay the federal taxes owed.
To access your current or prior year tax returns sign onto the TurboTax website with the User ID you used to create the account - https://myturbotax.intuit.com/
Scroll down to the bottom of the screen and on the section Your tax returns & documents click on Show. Click on the Year and Click on Download/print return (PDF)
Federal taxes owed can be paid on the IRS payment website - https://www.irs.gov/payments
Taxes owed on a 2019 tax return had to be paid on or before April 15, 2020. Payments after that date are liable for failure to pay penalties and interest on the unpaid taxes. The IRS will send you a bill in the mail for any penalties after they receive your tax payment.
