I got breast augmentation surgery in November 2017. Can i add that to the did you have medical expenses over $2,700 part? This is on the deductions and credits part.

If this was an elective surgery then no you can not add it as a deduction. Cosmetic surgery is specifically excluded from being deductible. If it was medically necessary then it is deductible.

  "You may deduct "Medical care expenses for the diagnosis, cure, mitigation, treatment, or prevention of disease, or payments for treatments affecting any structure or function of the body. ......You may not deduct funeral or burial expenses, over-the-counter medicines (i.e., medicines or drugs that aren't required to be prescribed), toothpaste, toiletries, cosmetics, a trip or program for the general improvement of your health, or most cosmetic surgery. You may not deduct amounts paid for nicotine gum and nicotine patches that don't require a prescription."https://www.irs.gov/taxtopics/tc502
