I converted roth 401k rollover to roth ira. The taxable amount on my 1099R is 0 and the distribution code is an H. TTax is treating like it's taxable.

These answers don't help.  I did a direct transfer from a Roth 401(K) to a Roth IRA. 1099R has 0 in box 2a and H in box 7.  TTax is treating this like a taxable event increasing my taxes due by over $7000.  Just for grins I entered G into box 7 it is no longer taxable.  How can I enter this correctly?
