Can I input last year's tax return?
how do i enter my 2018 tax return for reference?
Please explain what that means.
Are you asking how to transfer the data from last year's 2018 return into your 2019 return? Was the 2018 return prepared in Online TurboTax?
If you are in the same account as last year, the 2018 data should have transferred in automatically when you started the 2019 return. If it didn't, you may not be in the right account.
Do you see evidence of the 2018 return in that account when you go to the Tax Home and scroll down to "Your Tax Returns & Documents?" If not, we can tell you how to look for multiple accounts.
