I second @rodr's comment. Your board will assist with any questions you have, and even the PE's in your office might have some experience since they have to submit PDU's yearly. Write out your SER and have the PE's in your firm review it. They can sign off on your past experience if they review...
So you didn't have to complete the application twice? The website says to complete the online application in entirety even if you're sending info from NCEES.
Did you send in your NCEES record, references and work experiences before or after your TBPE application?
