1. ITR 1 for AY 2018-19.

To claim the refund for last 6 years....... you can file condonation requests (each for every AY) to Jurisdictional ITO for delay in filing the returns (u/s. 119-2-b of IT act) & allow her to file return to claim the refund.
If permitted, you can file the earlier year returns, and claim refunds.
