Importing a 1099-B, TT does not understand "sell to open". I am having to reverse the date of open/close on all of these. Anyway to autofix this?

There isn't a tool for this.  Short sales are manually corrected, unfortunately.  The date you acquired is the date of the sale (or the expiration date) and the close date is 24 hours later.  You'll have to go through and manually fix these.

in order to manually fix it 

Click on --View, then click on forms and look at the errors,

OVERDIDE it as necessary.

hope this helps

some brokers issue a correct consolidated 1099-B and some do not.

You should switch to a broker that does it correctly.
