Cellular Device on an installment plan

Hello,

I'm a gig worker and I bought a new device and new service with a different carrier so all of the business related work is done on that device/service. So it's 100% business.

What I am unsure about is how to itemize the cost of the phone itself which is being paid via an installment plan.

Do I deduct the total cost of the phone for the 2022 tax year even though I'm still making payments or do I only deduct what I've paid so far?

Also, in the communication expenses section do I put my cell phone service there as well as the phone and related accessories (case, screen protector, etc) there or do I leave the service costs there and put the hardware and what not under an another category?

Thank you
