My bad. I am talking about Sch C. I took the actual auto expenses deduction instead of the standard mileage. However, the standard mileage deduction is better than the actual auto expense. Considering this, can the return be revised/amended now and if so, will I get additional refund from the IRS and State (Massachusetts)?
For the previous years - 2016/2017 standard mileage method was used on Sch C.
