If you don't find your 2018 tax return in a different account, see the following FAQ for some other possibilities.
Why can't I find my return in Tax Home or My Docs?
Did you use TurboTax to file your 2018 tax return? If you used other software, or someone prepared the return for you, it won't be in TurboTax.
Of course, if you can't find your 2018 tax return anywhere, there is one last possibility. Maybe the IRS is right. Maybe you never filed for 2018.
