Retirement tax questions

This is a follow up to a similar situation, what if I have a employer ROTH , BOX 12a , AA , for $XXXX.xx , AND a separate ROTH at a brokerage that I make annual contributions to as well. That area in the deductions section asks for the total , what would I put in what box in that situation ? 

thank you , I may start a new topic if I get no response's.
