1120S - Error Related to UBIA

When running error check on my 1120S, I get the following: 

 

Form 1120S p3-5 - 199A Sum Wks (Page 1): UBIA - The total amount is larger than the amount allocated to all Schedule K-1's. Review the K-1 Statement to ensure that the combined K-1 amounts for this item are increased by [amount of UBIA]. 

 

I only have one K-1 for this business, and the UBIA is automatically calculated. How do I fix this? If I proceed to file without correcting the error, TT deletes the number from the UBIA field completely. 

 

Thanks for any help.
