You need a lot more help than we can provide in this forum if you have not been filing tax returns for "5-7" years.
If you had even $400 of self-employment income in a tax year, the law is that you were supposed to be filing a tax return and paying self-employment tax for Social Security and Medicare. You could have prepared a schedule C to deduct your own business expenses. Depending on how much you earned, you may also owe ordinary income tax for those years.
Each tax year has to be filed on a separate tax return using the forms for that specific year, so there is no such thing as just putting all of your old W-2's on one tax return and sending them in together. It is too late to receive a tax refund for any tax year earlier than 2016, but if you owe tax due then the IRS still wants you to pay.
You can check to see if there is an order for your federal refund to be seized for your student loan debt:
NOTE: You can contact the IRS Treasury Offset Program Call Center at 1-800-304-3107 to ask if they have an offset for you on file. TurboTax would not have that information.

It is unclear why you have been driving "100 miles one way" -- but commuting to and from work is not deductible--but if you drive during your work day to perform your work -- if self-employed--then you could enter your mileage on a schedule C as a business expense. But you need some written records to show your mileage and vehicle expenses.
Car parts? We do not know what you have in mind for claiming car parts.
Court cost and fines are not deductible.
You should seek the help of a local paid tax pro to get your issues sorted out. The longer you put it off, the worse this will get.
