Correction on submission to SARS on individual return

My Fiance received a travel allowance last year, due to seeing patients at home, she submitted her tax return before putting in her car value along with her mileage that she needs to claim, and hence didn't get any rebate from SARS. Is there anyway in which we can ask for a correction on the tax return from SARS, or what should we do? I am sure she should be due a rebate.

Yes, she needs to go into SARS eFiling and navigate to her Tax Return (go to Returns history) and she should see a tab called "Request Correction" which will enable her to make the changes.
