Amending an amended tax return

1.  I filed my tax return in March

2.  We received a Form K-1 today, April 14

3.  I submitted an amended return this afternoon, including an e-check

4.  Later found out that I had mis-read the K-1to my disadvantage

5.  Walked through the revised tax return with a relative by updating my original return

6.  Once I did that, I tried to file an 2nd amended return using the Amend function

7.  TurboTax told me that there was no change to my tax return - probably due to my run-through with my relative

8.  I removed the K-1 info from that original tax return, and re-did the 2nd Amended form.

9.  I do not get the option to e-file that 2nd Amended form

HELP!!
