What is the best and most efficient way to enter sales reported on 1099-B with boxes A and D checked if they include wash sales? Can I use the section for Form 8949 Reporting Exception Transactions on the Capital Asset Sales Worksheet for summarized entries with Box A or D checked if I have wash sales? Is it best to attach a pdf of the brokerage statement?

You can. Does A and D mean covered sales?

I just reduce the basis by the wash and plunk them right in the summary boxes at the top.

As long as your gross proceeds match and youve got the correct gain/loss at the end, you wont hear a peep from anyone.

Thanks. Yes A and D refers to covered sales. It sure would be good if Proseries had better instructions on how to do this. There are 8 pages of transactions for covered sales. Should I attach them as a pdf?

Im a rebel, Ive never attached anything, and never had a client asked for any of it either.

there is a box to input wash sales on the asset entry worksheet

Maybe next year they’ll include a box. Bob suggested using the worksheet under the basis amount to list the basis and wash sale

I enter the totals as a line item sale and use the wash sale box there.

As a side note, maybe the stories aren't true. I heard that @Mimbreno had been kidnapped by aliens. It's nice to see you @Mimbreno , but how did you escape? 😜

In Pro Series Pro, enter sales on a 1099-B. Enter sales proceed and basis and wash sale amount. Enter dates or various (but not for sale date) and then you must check long or short, D or A.

I don't understand the question "How to enter these?"

I report them in the Form 8949 Reporting Exception Transaction box, netting them in the Cost Basis cell in a supporting statement. It is the wrong way to do it but it is very quick and the result is correct. So far the IRS does not seem to care.
