I am below 59. I earned $4200 on box 1 of my W2, although it says $4350 on box 3 and 5 because it includes $150 into a 401k. I also had $1750 on Box 7 of my 1099 for my side job. I may deduct about $100 of business expenses. Can I contribute the $5500 max for 2018? Do I have to be careful about deducting anything else if I contribute $5500?
