How can I add my 1099-B form from Robinhood provided by Apex if there is amount in "Wash sale loss disallowed" on the summary page and there are total >500 transactions?

if your import fails, you can switch to the CD/Download program which will handle 500 or more stock  transactions.

as an active investor, be aware that your category Box A sales without adjustments do not require Form 8949, so there is no reason to import those transactions.

instead use the "enter a summary" option to put your numbers on Schedule D Line 1a.

If you have wash sales, it gets more complicated since those have to be itemized on Form 8949 and the summary totals adjusted accordingly.

enter the wash sales on Form 8949, then use the subtotals on the bottom of that form to know how much to subtract. Be sure to NOT check the adjustments box in the summary window.

In Proseries basic, is there a way to only enter those wash sales or do I need to enter 46 pages of transactions??

complain to your broker, ask them why the won't give you two selectable reports to import:
transactions with adjustments and,
transaction without adjustments.
