I have Form 1099-B which lists short term transactions for which basis is not reported to IRS. This is through my employers RSU plan which was vested on various dates during 2020 and I sold them through 20 transactions.
There is a supplemental stock plan lot section in the tax document. Fidelity has listed other fields like adjusted cost basis for each of the transaction.
Question: Should I use adjusted cost or other basis from supplemental section and fill it in Box 1e in TurboTax?
Eg. each transaction in TurboTax by selecting 'I'll enter one sale at a time'-
For first transaction - Box 1d is Sale proceeds , Box 1e is adjusted cost or other basis field, Box 1g Wash sale loss disallowed $156, all other fields not applicable
Or should I select 'I'll enter a summary of each sales category' for total of all transactions -
Total 1d: 17321
Total 1e: 13083
Total adjustments 1g: 3347
