Form 8990 is required for individual taxpayers who receive a K-1 showing Excess Business Interest Expense in Box 13K. However TurboTax still does not support Form 8990 for individual taxpayer products in tax year 2021.
I understand one could fill out a paper form and include it when printing and mailing a return, but this eliminates the benefits of having the form automatically completed and electronic filing.
I hope TurboTax will add support for Form 8990. I will note that TaxAct (a competitor of TurboTax) does support Form 8990 in all editions. (See https://www.taxact.com/individual-taxes/download/self-employed )
