Filing an Amended Return

I had to complete an amended return both federal and state. When I finished and  was ready to file it says I have to mail federal and I can email state which is for Oklahoma. That's as far as I could get, first saved return, printed return then when tried to file it says I can't e-file federal because I am at the limit of 5 e-filed returns. Go back and select file by mail and continue, still says I can't efile because I am at limit of 5 e-filed returns. Seems to be a turbo tax problem with the software. Now stuck at this point of not being able to file.
