Get your taxes done using TurboTax

Just getting around to doing this.  To review...

I am using the downloaded TurboTax which is installed on my PC.

I have saved copies of my 2023 federal & state returns in a non-TT folder with new names.

When I open TT and login, I shows me an icon for the 2023 tax file but when I open it the system tells me my return submission has been accepted.

How do I get/create a return where I can plug in anticipated numbers for 2024 to get an idea of tax impact?

I am envisioning a file with data entries for 2023 which I can replace with estimates for this year?!

Thanks for your continuing guidance.
