You should probably seek professional advice. That said, the long and short of it is that you should expect a 1099-MISC and the money will be taxed as personal income on a single tax return. Remember, DBA is an alias for you personally. It makes no difference which account the money lives in, and the concept of paying yourself from the DBA is nonsense. You seem to think that maybe a DBA is some kind of LLC-lite and it absolutely isn't. It is not even a separate entity. The DBA just says: "dear IRS, sometimes I'm Bob and sometimes I'm Dave, but they're both me so don't separate the two."
Note for the future that the core identifying value is your tax ID number, which in the case of a DBA is your social security number. A separate return requires a separate tax ID, which in turn involves a somewhat elaborate registration process.
