@mattbutler0220 In your post above you said that " they did not calculate correctly"; now you say the return was never submitted. Did you e-file? What does it say in your account?----Does it say the return was "accepted," "rejected," "printed," or "ready to mail?" If it says anything other than accepted, then you did not e-file it successfully, so that explains why you owe tax due with interest and penalties. If the return showed that tax was owed---how were you paying the tax? Did you mail a check or money order? Pay online at the IRS site? Did you check your accounts to see if the money was paid? Or did you enter banking information for a direct debit that did not occur since the return did not go to the IRS?
What tax year was this for? You say "a few years ago" but do not mention a specific tax year. Was it for 2021? A lot of people made mistakes on their tax returns that year because they were very confused over the stimulus checks, the recovery rebate credit, and the advance child tax credits, among other things.
What mistakes are you saying TT made? The user is the one who has to go all the way through the FILE section to click a big orange button that says "Transmit my returns now." If you did not do that, then your return was not e-filed.
When you e-file your federal return you will receive two emails from TurboTax. The first one will say that your return was submitted. The second email will tell you if your federal return was accepted or rejected. If you e-filed a state return, there will be a third email to tell you if the state accepted or rejected your state return.
If you still have not filed the tax return, you need to do so asap. A past year return can only be filed by mail. You need to print it, sign and date it in ink, and mail it in.
