When I sign out ... at the top right of the Turbo Tax page ... it says I have to file by 2/15 in a red triangle ... how do I interpret that ?

You are seeing the date for the special free offer to use online Basic Live for free if the return is filed by 2-15.

You are posting from a higher version--online Live Premier -- you are paying for that version and do not have to file by 2-15
