Wrong return ITR form

Dear Sir 

     My ITR filed in ITR 1 Sahaj instead of ITR 2 since I am having capital tax gain.Capital tax gain shown in other income and tax filed as per slab.All income is matching with AIS and 26 AS.My return is processed and I got my refund. Now I noticed that wrong ITR form is used. What remedy l have? Since my return is processed can I leave and forget ?
