I made Extension payments not using Turbo Tax. Where in Turbo Tax does it allow me to enter Federal (Form 4868) extension payments made? And were for State also?

I had a similar situation, DoninGA resolved my issue below

For 2019 taxes owed paid in 2020, use the procedure for reporting a payment made with an extension.

To enter, change or delete a payment made with an extension request (Federal, State, Local) -

• Click on Federal Taxes (Personal using Home and Business)
• Click on Deductions and Credits
• Click on I'll choose what I work on (if shown)
• Scroll down to Estimates and Other Taxes Paid
• On Other Income Taxes, click on the start or update button

On the next screen select the type of extension payment made and click on the start or update button

Or enter federal extension payment in the Search box located in the upper right of the program screen. Click on Jump to federal extension payment

The federal extension payment will be shown on Schedule 3 Line 10. The amount from Schedule 3 Part II Line 14 flows to Form 1040 Line 18d
