How could i get a copy of my Turbo Tax file from 2007 that i did online?

TurboTax and the IRS only keep copies of tax returns for the past 7 years.  So your 2007 tax return is no longer available.

Thank you so much. I AM SO FRUSTRATED. im trying to find out why i didnt get a stimulus check. The IRS has a different address for me. One that i dont know. So they cant get into my file. Wtheyyy???

If you have not filed a tax return since 2007, do not receive Social Security or SSI, you can use the non-filer site to get a stimulus check.
