In my humble opinion, your advice is mistaken.
First, you are getting rid of the diagnostic error by arbitrarily and likely erroneously entering a zero in the US Source Income. Instead, @hntrust needs to get either the Total Gross Income or US Gross Income from the preparer of the K-1. (Total Gross Income less US Source Gross Income is equal to the Foreign Source Gross Income; enter either Total or US and TurboTax will calculate the other for you.)
Second, there is no need to change the code on AMT Foreign Taxes Paid from Z to B. TurboTax does nothing with this amount by itself. If @hntrust is subject to Alternative Minimum Tax (AMT) then he’ll have to utilize this and other AMT adjustments by entering them manually in the appropriate schedule(s). In fact changing the code is just simply wrong. ( @hntrust says that he’s already input a Code B amount.)
