Turbo denied my state tax due to some issue in their system now IL says I owe them $1100 for unpaid taxes for 2018/19. Since I didn't use Turbo this year they won't help.

you'll have to pay what you owe. it would have been paid in any case. before filing a claim against TurboTax for penalties and interest, read the filing instructions for Illinois that were with the 18/19 returns. they might have indicated you need to send in payment or pay thru its website, not TurboTax.  in such a case your claim would probably be denied.

I have / would have had no problem paying but for those 2 years I tried to fix the Turbo software issue didn't even make me aware I owed any money. So i was just curious how that would have happened.. Thank you for the response

Your question is really unclear.  Turbotax can't "deny" anything.  If you prepared a return and e-filed it, the state might reject it if some piece of information fails to match their expectations.  In that case, you print your tax return and mail it in.

If you never filed a 2018 or 2019 state return, they might be assessing tax now based on what they think your tax return would have been, by building a virtual return based on your wage information from the IRS.  If you can prepare a 2018 or 2019 return, you may be able to show them less than you think, or even that you are due a refund.
