I do not see my old returns in my docs

That's common to end up with multiple accounts. First LOG OUT of whatever TurboTax account you're logged into right now. Then use this TurboTax account recovery website to get a list of user ID's for an email address. Run the tool against any email addresses you may have used

If you used the Desktop CD/Download program then the only copy is on your computer and not saved or stored online.

When you log in and scroll down you should see all your prior years in THAT account ... so if you do not see them look in another account ...  

Make sure that you are signing in to the same account you used to file your tax returns.  Some TurboTax users have multiple accounts.  How do I access a prior year return?

Here's how to find out which TurboTax accounts are linked to your email address:

1. First, sign out of your account (otherwise, you'll be thrown into a loop in step 2).
2. Go to our Get help signing in to your account page, enter your email address, then continue.
3. Check your inbox for a Your TurboTax Account email from do_not_reply@intuit.com, which will list all Intuit accounts tied to that email address.
4. Repeat these steps for any other email addresses you may have.

If you have multiple TurboTax accounts, pick one and stick with it when you do future tax returns. That way we can automatically transfer your tax info over year after year. It also makes accessing your prior-year returns much easier.
