I can't find "Tax Home" to get a copy of last years return.

If you are using TurboTax Online, you can find your TAX HOME on the left side panel.  When you login to your return, be sure to click Continue or Pick up where you left off to open up your account.  From the main page, scroll down and you will see Your tax returns & documents.  This is where you will find last year's return.
 

Please see this TurboTax Help Article: How do I view, download, or print a prior-year tax return?

If Tax Home is not one of the items in your left column menu, it means you have not yet started a 2024 online return in that account.    Act like you want to start a 2024 return and start answering the questions.  You may have to even choose a product (but you don't have to use it if you don't want to and don't have to pay.).  A few screens into the interview the Tax Home tab should appear in the left column.
