I believe you will be fine.
Let TT compute the return and review it.
The instructions indicate "if line 3 includes income from guaranteed payments....."
Guaranteed payments in general are an expense of the partnership not income.
What the instructions are most likely referring to is if in a tiered partnership context, the partnership received a K-1 with guaranteed payments (income) then subtract those out on line 7.
Instructions are not always the model of clarity.
