Filed extension, filed state in Oct, paid taxes that turbo tax said, got letter from state for penalty and interest
As the title says.
I'm so confused why I now owe additional penalties and interest to the state. I filed my extension through TurboTax in April, so TurboTax knew I had filed an extension.
When I filed my state return in October, unbeknownst to me, TurboTax did not put the checkbox on my return that said I filed an extension. So I was charged a penalty by the state that I just got a letter for.
Additionally, TurboTax did not calculate the interest I owned for the late payment. So no additional fees or interest was added to my state payment. Again, all of this was unknown to me.
I assumed, and I think fairly, that by me purchasing this software, that it would correctly indicate that I had filed an extension, and that it would see I was making my payment late and calculate the additional late fees and interest and add that onto my payment amount.
Having just got this letter from my state, I know owe additional fees and interest, because in my opinion, TurboTax failed to do what I would consider a basic feature. I just made the additional penalty and interest fees payment to the state to avoid any more shenanigans and interest accrual. However, I am quite unhappy with how this all played out.
What are my remedies?
If TurboTax can't figure this stuff out properly, is there alternative tax software that does, and that I can rely on to file my return properly and calculate my payment owed properly?
