When filing Form 1120 for a cash-method C-Corp with conflicting revenue/expense sources: (1) identify the authoritative source (typically bank deposits/expense sheet over invoices), (2) systematically map each line to corresponding Form 1120 schedules (J, K, L, M-1), (3) identify critical gaps (BOY/EOY cash balances, capital structure, prior retained earnings) that block filing, (4) use bank statements to close Schedule L gaps, (5) flag estimated tax penalties (Form 2220) when payments were $0. Prioritize Schedule L completion since total assets >$250K triggers filing requirement.
