How do i find out many efiles i have used with my current turbotax?

The IRS limit is five federal e-files.  How many have you e-filed?  Subtract that number from five.  There is no way around the limit of five.  If you have more returns for family members etc. they have to be printed, signed and mailed.

Try going to File-Open.  All the returns should be listed in the big box.  You might be able to tell just by looking through the list which ones have been completed and efiled.

No one has answered the question.  I prepare a few returns that I consider efiling but don't.  

Does Turbo Tax show how many efiles I have left?

You are posting your question from online TurboTax Deluxe.   It is with the CD/download that you get five federal e-files.  What software are you really using?
