The taxpayer took out $50,000 from Bank A, which sent a 1099R showing it all as taxable and also "taxable amount not determined".  Code 7. 

He rolled it over a month later to Bank B, which shows the rollover contribution.  It should not be taxable but if I show the $50,000 distribution and put 0 taxable, I get an error message.  How do I report this?
