XterraTom: Itemizing deductions on Schedule A is for certain personal and employee related expenditures. Your mystery shopping is neither of those. Your mystery shopping is considered self-employment income and the proper tax form for it is Schedule C. Schedule C is where you list your income and expenses, and come up with a net taxable income that is used to calculate your self-employment tax and is added to the rest of your income to calculate your income tax.
You should absolutely keep track of every last dime of income earned, and every last dime of expenses that you incur. Mile driven is an expense, keep track of the miles you drive for your business. You can still build an accurate accounting for your miles driven for 2024 using Google Maps and a record of the shops that you did. In 2025 you can start from the beginning and keep a log of your miles driven. You should also be keeping track of your other expenses that you incur from the operation of your business.
Do a search on this site and read the threads on taxes. It will be worth your time.
