K-1 loss increased my amended 1040 tax return from the original. Why?

I submitted my original 1040 individual tax in March 2025 and paid the full owed amount then. Received a K-1 late in June 2025 and had to upgrade to a Premier version from a Deluxe online to amend my tax return yesterday thus paying a fee of $35. I had a $1212 loss on my K-1 Sch. 1065 (entered as a negative) and it shows I "owe" $910.  Nothing else changed. If I had a loss why am I paying? I already paid $1230 with my original filing in March and now on top of that it's asking for $910 though I had a loss. Can anyone explain?

By the way, a TurboTax Accountant walked me through the process of amending/including the K-1 yesterday as I wanted to make sure it was done correctly the first time. He didn't notice it or was in a hurry for his feedback.
