The code V is associated with qualified business income (QBI). That would likely mean the income reported in box 1 on your K-1 schedule is at least partially QBI income, but you may have to ask the issuer of the K-1 schedule to be sure.
You should report the gross receipts (AC gross) if it is listed on your K-1 schedule, same for Excess business loss limitation (AJ). Can you clarify what you mean by aggregate deductions?
