Wrong return ITR form

A taxpayer mistakenly filed their Income Tax Return (ITR) using ITR 1 Sahaj instead of ITR 2, due to capital gains tax being declared under 'other income'. Despite the incorrect form, the return was processed, and a refund was received for FY 21-22 (AY 22-23). The taxpayer is now seeking advice on whether there are any further actions required or if the matter can be considered closed since no dues are outstanding and no further intimation has been received.
