Turbotax messed up our 2021 NJ NY calculations as well (taxes paid to other jurisdictions).
It used a wrong amount in income actually taxed by NY (combined both of our incomes, earned in NJ and NY, not just NY) on NJ-COJ, resulting in using 70% instead of 37% for maximum calculations. Got audited by NJ and now own interest for 2 year and penalty, besides the underpaid tax. So much for 100% accuracy guaranteed.
