Retirement tax questions

My 1040 5a also does not show the word ROLLOVER.

 

I've done an after-tax contribution of $38,500.  And an in-plan ROTH conversion within the 401k.  No IRA.  There would not be a form 5498 submitted by a financial institution since this is not an IRA.  Do I need to worry? 

 

The 1099-R is correct:

Box 1 38,500.00

Box 2a 0.00

Box 5 38,500

Box 7 Distribution Code is G.

 

On the 1040:

5a is 38,500.00

5b is 0.00.  

 

I noticed this a few hours after E-filing via Turbotax Online Self Employed.
