Handle your wash sales and generator your Schedule D

If I want to upload short-term trades on Schedule D(not Schedule D -1) – How can I do this and efile with this?

You can manually enter the short-term trades into TradeMax, then Export a TXF files to other software which support Schedule D to generate schedule D.

Or just generate a Schedule D-1 form in TradeMax based on this short-term trades data, then number this report as an attachment to Efile with Schdule D.
