itr 4s is better option, show income whatever you want to but not less tha 8%( section 44ad) select itr 4 in case maintaining books, or shoeing income less than 8%, but if less than 8% audit will also be required along with maintaining books.
so go for itr 4S. simple to fill, no need of books maintaining, and easy to claim refund if any
