My husband was granted NSO stocks before his company went public and when the company went public our shares were converted and we decided to sell some last year. Since I was new to company stock, I did not know about the Stock Plan Transactions Supplement or that I should have entered the sales individually. I entered the 10 transactions as 1 since I sold them on the same day and just used the total line on the 1099 from E*Trade (which I now know was wrong, since we sold more shares this year).
Here is my problem.... I need to amend my 2023 Return to correct my error, but when I go to Turbo Tax to amend my return, I only have 1 line to correct since I entered the stock sales as 1 transaction instead of 10? Do I have to find a way to calculate the transactions into 1 or is there a trick to enter the other transactions? Also, there are 13 adjustment codes to select , what do I select O - other adjustment not listed)?
Thanks for your help
