Belated itr return of ay 18-19

I have created the profile for my wife in income tax site last month only. Upon viewing the 26 AS for the assessment year 2018-19 i found that bank has deductes tds from interest on fixed deposit. She doesn't come under the purview of income tax. She is not employed and the only income is interest from FD which was around 1.1 lakhs that year and bank deducted Rs 1155 from that. We forgot to submit the 15G that time and hence it happened like this. Return was not filed for the AY 18-19 .Now ,Is there any way to claim refund of the tax deducted. Well I tried myself by downloading the excel utility of ITR 1 for AY 18-19 but at the time of uploading, it asks for condonation order. How I could get that order.?? I tried through My account>>service request>>New request but it shows "No records found". Kindly help to submit the delayed ITR
