TurboTax K-1 error: Previously disallowed QBI must be manually calculated

I am getting the above error message after completing input for a K-1 form. However, I do not have any previously disallowed QBI. How can I clear this error?

 

The K-1 is for a real estate limited partnership that I am a member of. There is a small amount of passive income. I have never had disallowed QBI. There is no at-risk liability. Box 20 is checked for A, Z, and AH and that information is entered.

 

I have three such partnerships and am getting the same error on all three K-1 forms. These are a few years old and I don't recall ever having this error before.k1error.JPG
