You for sure need to get an accountant or a tax professional to help you. Although folks do it, January is not the best time to be asking what sort of things you need to track for taxes concerning your business. Unless of course you just this month started selling. Trying to remember all your different expenses, that because you didn’t know they were expenses is a hard way to learn to track everything daily/monthly.
You may want to go to the IRS website and look for instructions etc. on filling out a schedule C which will give you a better idea of everything you need to be tracking. If you didn’t do it last year, at least start tracking it now. IMHO you should track these things on your own spread sheets in your computer rather than depend on whatever sheets Amazon produces for you, especially if you sell elsewhere.
