SAVE YOUR TAX RETURN !

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.

You may have to start a 2020 tax return before the links on the Tax Home web page become available.  In that case start the 2020 tax return with the User ID you used for the 2019 return.  Once some basic information has been transferred over, Tax Home should be visible on the left column.  Click on Tax Home and then the other links will be shown as in this screenshot.

To access your current or prior year online 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)
