Thank you for the TaxAct suggestion. Tax year 2021 was the first one I had to file 5471 after so many years of being a loyal TurboTax customer. And after TurboTax's non-support of 5471, the non-ability to e-file my return, and the impending months and months of wait time for my refund because of this, I will be switching to TaxAct for tax year 2022
