There is a qualified disaster relief credit called Credits for Affected Disaster Area Employers, Form 5884-A, that is reported under the Code P you mention on the K-1 Box 13.
The IRS earlier called it Employee retention credit and TurboTax may still be using that title. That's the credit you are looking for and entering the $$ there will cause the pass-through credit to land on Form 3800, Part III, line 1aa (and the 3800 refers to it as Employee retention).
