I've gone about as far as I can go with this. I don't know where you are getting 14%. I trust T/T to plug in the numbers you give it, but if you're still unsure, it might be worth it to your peace of mind to upgrade with them to have one of their people go over it with you. Also, @UberTaxPro
does returns for members here. You can pm him for details.
I did notice that you're listing about 2500 miles more than Uber shows for online mileage. Do you have a contemporaneous log to support your claim? If not for the taxable debt cancellation, you probably wouldn't be paying income tax, but rather just the SECA contributions.
I'm no expert, but some of the things you've claimed as expenses for ride share might raise a red flag, such as "assets" "supplies," and communications." The latter is probably your cellphone bill. Are you aware that you need to prorate those bills if you use the phone for both business and personal calls, data, gps, etc? Similar to how the SMR deduction is only for business mileage when you use the car for personal travel. Do you have receipts for the supplies? Just saying, be prepared to support and defend the expenses you claim.
Just saw your edit to your post. The "SE" 14%, if you're ta about self employment, is the 15.3% SECA contributions I mentioned earlier. You can't avoid SECA, based on your profits, and aside from that, your income tax is nominal.
These extra screenshots don't look like they match your situation or numbers. ???
