So my return is on hold because my 1099-R has a BL in section 7. Any ideas on what I can expect to come of this or should I do something?

Code BL is a loan from a Designated Roth treated as a deemed distribution.    What makes you think the IRS is questioning that or holding processing because if it?

Were you under age 59½ at the time of this deemed distribution?  A Form 1099-R can only have codes B and L together if you were over age 59½, otherwise the form was prepared incorrectly.  (If you were under age 59½ it should have codes B and 1.)
