Tax Question: this is the first year that TurboTax generated a Form 8453 for me with Form 8949 (Sales and Other Dispositions of Capital Assets) checked. Form 8949 was electronically filed but I just noticed it says "Vanguard-See attached statement". The gains are in VG mutual funds and I received a 1099-B with Box A checked (indicating basis was reported). I don't think I need file this with a schedule listing all individual transactions, but I'd like some confirmation. Is there something I should do differently to avoid this in the future? Thanks for any insight.
