1099R

I received a 1099R with the following boxes:

1 gross distribution $ 10,000

2a taxable amount $ 2,000

2b total distribution box checked;

7 coded G

 

The $10,000 is the payment from 403b to rollover IRA

The $2,000 is the payment from 403b to RothIRA, conversion portion.

 

I input the above $ and code, and the $2000 amount did not allocate to the conversion ira in form 1040, 4b.

How do I fix this? please advise.   Thank you.
