you must submit the following items to DMVs your Request for Approval of Driving School Name form MV-299.3 that shows your Driving School name was approved by the DMV see " Driving School Name Approval " aboves a completed Driving School License Application  form MV-521
I attempted to do it online but encountered a technical issue. Is there another option where I can submit the following requirements to DMV?
Certainly, you can mail a Request for Certified CDL Abstract PDF MV-CDL form along with the $10 fee to the DMV to the address provided on the form, or have your employer order your CDL driving record abstract through LENS.
Is this abstract official? Like I won't need anything else to prove this information?
