I am using 2019 Proseries Basic.

I am using the summary page from the broker for the sale of stock (short and long term) - basis reported to IRS, etc. for inputting the summary sales  in tax return versus doing 25 indivual sale transactions.

Do I have to attach the summary stock page to the return?   Is it mandatory IRS requirement?

If so, can you give me instructions?

Thanks,

John
