Very strange.

Do you have the IDC amortization linked to the partnership?

When you say Lacerte changed your K-1 input, you mean on the Federal K-1 Reconciliation worksheet, the topmost left-hand cell doesn't match your Screen 20.1 input? Is the amount it's off by a number that has meaning to you? The amortized IDC shows up three lines lower?

Do you have any diagnostics that might be relevant?

I'm poking around at a dummy return, and can't reproduce that 6198 adjustment or the Reconciliation Worksheet weirdness. If this is a very large return (lots of line-items), sometimes Lacerte can break in weird random ways that are specific to you. I figure out what the answer should be and judiciously override, making a note in my file as to what the carryforwards should be.
