Tax Year 2020 - My total proceeds for my 1099 from stock trades is over limit. How do I fix this to submit through turbo tax?

Yes, TurboTax sets a $10,000,000.00(actually $9,999,999) limit in the data entry for Schedule D (capital gains and losses), but you can still enter the stock sales over the program limit.  All you need to do is to break them up into a series of smaller transactions or individual group of securities sales that should not total more than 10-million dollars, Turbo Tax program will accurately add up the group of securities on your Schedule D that will equal your stock sales.. You may group your stock sales  in 2-3 different securities.

So just to be sure, I can divide my Proceeds by half and submit those two times in order to fit it all and it should calculated the same?

Yes, you may divide it into 2 group of securities that will equal the amount of your stock sales without going over the program limit.  Please, message us back if these steps solve your issue.
