Can i access my previous years' tax returns?

  You have to access your own account and/or  print it for yourself using exactly the same account and user ID that you used when you prepared the return.

Start a 2024 return online and enter some personal information  so that the menu on the left opens up and lets you access your past year returns.

Many people have multiple TT accounts and forget how to access them.  Log out of the account you are in now.

SAVE YOUR TAX RETURNS !

EVERY year before mid-October you should save a copy of your tax return as a pdf and print a copy of it for your records.  That way you will not be searching online frantically when you need it for a lender, FAFSA forms, your next tax return, etc.
