YOUR INSTRUCTION ARE CLEAR ON HOW TO DELETE ONE FORM AT A TIME. IWANT TO DELETE MORE THAN ONE FORM AT A TIME!

Basically make the entry you want to delete a null entry.......Here is what I did...Just for the description put no entry - blank line .  Say purchase and sell date 1.1.2020, say purchase price and sell price both 0.  Basically make a null entry.  I found no way to delete a line in the middle of other transactions which is a ridiculous limitation of the software.  Good luck.

You can do a search for 1099-b and use the Jump to 1099-b link to see a list of all the 1099-b forms listed on your return.   Then use the Delete button or trash can icon to delete the entire form.   

Also, if you are using the desktop software, you can click on the Tools menu at the top, and then choose ''My Tax Data'' to see a list of all of your forms, both manually entered and imported which you can delete.      @WNH1930nfa1948    @Ricoswave

That suggestion deletes the entire form.  I needed to delete a few blank entries among 20 transaction entries on the 1099-b.  I had mistakenly entered a couple transactions on the list and had to delete lines in the middle of all entries and could not find a way to do it other than basically entering a "null" entry that would not go anywhere and just be a placeholder.  So just enter null meaning less data and it will take care of the problem.

To the right of the "Edit" icon there is a "Delete" icon (trash bin). But it didn't show up for me until i expanded my window.
