I’m a Nanny! Anyone else experience doing their taxes with this?!

Ok! I feel like an idiot! Basically I became a Nanny last January! I had to buy a larger vehicle because there are 5 children. I don’t get reimbursed gas expenses. I am being taxed, and paid via BreedLove pay services weekly with a pay stub. I make $20/hr. ($400/weekly-tax=$325/weekly). My boyfriend was shocked when I said I never really get gas receipts, but I’ve already put nearly 9,000 miles on my vehicle since late March, and now it’s October 3. That’s A LOT to me! Do you get reimbursed for gas/routine maintenance? I pick them up, drop off, activities, DID I MENTION THAT THEY GO TO 4 DIFFERENT SCHOOLS?! Lol! A very large amount of my money goes towards gas. I have a second, and temporary third job because I’m constantly having to buy gas. I also didn’t know if your payment for prescriptions and such should be documented as well! It’s kind of hard to get in touch with H&R; Block, and when I google it it’s really just advice for my employer more than for me about not being tax evasive. Can anybody help?! Thanks!!!
