You will need a copy of the actual forms filed. Not a summary. The other person who replied is correct, to amend a return, you have to fill out what was previously filed along side what the new numbers should be. So Turbotax will need to know what the original numbers were. In order to make sure they match, don't go through the questionaire, just hit "go to forms" in the tabs at the top of the page in turbotax, and fill them out exactly as your copy shows. Then tell turbo tax you filed by mail, then fill it out the new way. Are you sure the law allowed for a deduction for the capital gains loss in 2018? Does the deduction need to be more than the standard deduction? There may be other issues keeping you from getting more money back. You cannot get back more than you paid in. So you can't get back more than $2117. Sorry I am not much help here.
