Schedule D records can affect the final result
Realized gains, losses, carryovers, and capital gain distributions may affect final tax treatment.

Review note: Use calculator output as a worksheet, not as tax return support.
Topic: Calculator limits
Capital gains should be part of the professional handoff
Users with realized gains, qualified dividends, or fund distributions should add these items to the CPA review packet.
