Which tax deduction category should use for annual subscription costs for a Mileage Tracking App?

[DoGood]

I have rental properties in which I use one or more cars to travel to/from for maintenance and repair visits. I use TripLog App for Mileage Tracking which has an annual subscription charge to track my business miles. I use the standard deduction method for my miles. However, this mileage tracking log is more of an administrative cost rather than a specific vehicle cost. Or is it?

Which tax deduction category should be used for the cost of mileage tracking apps/services?

If none of the pre set categories in the Sch E  sections works then you can simply make your own category at the end of the expenses section.
