There is a limit of $10,000,000 I can input into investment proceeds and costs in Turbotax. I found someone online mentioning this workaround (I don't know if I should share links here so I am attaching the screenshot). The tax will be the same. Will IRS have problem with this method? Thanks.
No, the large numbers of proceeds and cost basis on 1099 are because of the high frequencies of trades, not the account size.
If anything, the evidence would seem to suggest increased trade frequency may correlate with decreased account size
Possible solution? https://ttlc.intuit.com/community/i...ept-the-numbers-for-shares-and-net/00/161745#
