Can my cell phone, internet bill, or cell phone bill be a deduction for investment expense?

Can my cell phone, internet bill, or cell phone bill be a deduction for investment expense?

I just purchased a faster upgraded cell phone in the end of December because I do all of my trading on my phone using multiple platforms. I am a bartender and a mom and I use trading on a regular basis to supplement my income.

Can I use those as investment expenses?

Also, I use robinhood, has anyone else noticed that the gold membership charges seem to be going under margin interest? Is this incorrect or should I put the $60 under margin interest as my tax statement says, or put it under investment expense?

Thank you!
