I have been a ProSeries user for about 30 years.  I have decided to retire.  I see turbo tax will only (IRS actually) let you efile 5 returns.  Can I keep my EFIN and PTIN number and use maybe ProConnect as a non paid preparer to file these returns (probably pay per return in case they all don't use me)?  I will have 5 different states also.  OR...will Turbo tax let me efile more with an EFIN number if there is a place to enter it?  I also thought about using ProConnect  or ProSeries pay per return for my own to finish out my business taxes (sole proprietor) and using Turbo tax for the rest...I can maybe get my grandkids on a free file.  Sheesh!  this is complicated!  And then maybe after I get my final business sch c completed I will tell the rest of them to take a hike!  🙂  Any help and comments appreciated.
