There is no way to import the sheet directly into TurboTax. You don't need all the data for your taxes anyway, just the totals for the year.

That doesn't exactly help me out.

I have mileage I need to enter

Insurance costs

Cell phone

Fuel/Oil costs

There's nowhere for me to input any of that using Turbo Tax online with my cell phone (Samsung S22 Ultra). 

Also, the "experts" I've asked to help, were unhelpful as well. 

You would enter your self-employment expenses in the self-employment section. Click on the magnifying glass on the top right and search for "self".

Once you are there, you will eventually get to the expenses section.  Add vehicle expenses, and utilities (for your phone). Then on the next page, click start under one of them to enter the expense.
