2020 & 2021 income tax returns

I filed both my 2020 & 2021 income tax returns with Turbo Tax Online.  I used the Deluxe version.  I received an email for both years saying the Federal & State were accepted.  Towards the bottom of the email, it said that if I wanted a copy of the return for my records that it would be best if I printed or downloaded it by mid October of that year.  Does Turbo Tax hold a copy for 7 years online or will it delete them before then?  I can still pull up the 2020 return online, but it is 156 pages so I do not want to print or download it.  I also feel more secure having it online only.  What is your answer?
