using Google, with Montana and vehicle registration and COOP
...I found a reference to it on page 4 of:
https://revenue.mt.gov/Portals/9/businesses/fees/CGR_Guide.pdf
it appears to be a County Option Tax, code 14.
Also on page 17 of the following...though they indicate "COOPT" instead:

______________________________
Added later based on discussion below: The LVREG fee cannot be used as a Federal deduction in it's "Car Registration Fees" area on the TTX Deductions&Credits page...only the COOP is allowed to be entered there.
During the Montana interview, there is a specific page where you will be able to add in the LVREG fee as a Montana deduction.......but this is specific to Montana.
