Query for wrong business code mentioned in itr during fill up of itr-3 ( ay 2018-19 ) for lic agents

Query for Wrong business code mentioned in ITR during fill up of ITR-3 ( AY 2018-19 ) for LIC agents ?

 I wrongly used business code as " Life Insurance " in place of original code " General Commission agents, brokers "

My questions ...

1) Should i reuiqre to file a revised return of lic agents for the above related mistake or not ?

2) Do you think that For AY 2018-19, the refund process of LIC agents will be affected for such kind of mistake ( i.e, Wrong business code mentioned in ITR -3) ?

Regards.
