Excess TDS with wrong AY

Dear Sir,

By mistake I have paid excess Rs. 5300 as TDS under section 194J with AY 2018-2019 on 4th oct 2018 through onlibe mode. Now return of TDS needs no revision as IT return and all other activities are completed for relevant financial year with correct details.

How could I get it refunded or adjust now?
