Do I need to amend my federal return if there are changes to state return?

[taxnewbienj]

I have a quick clarification about amending my federal return -

I filed my federal return and then when I filing my state return I had multiple states to cover, but realized that I was missed entering the info for all the states, i.e., live in State A and work in State B so I had all the State A info but missed to enter all the State B W-2 info before I filed the federal return. 

However, I was able to catch the gap before filing the state taxes, so wanted to check do I need to re-file my federal showing the updates to tax withholding for State B? 

FYI - I did not owe any taxes for either Federal or the states.

It depends if you itemized on your federal return. If yes, then entering additional state taxes withheld can change your itemized deduction. If you have any changes then you can file an amended federal return after the original return has been processed. Please see How do I amend my federal tax return for this year?

If nothing changed on your federal return then you won't need to amend it.

Thanks @DanaB27! 

I had standard deduction on my federal, so sounds like no change or amendment required to federal return?

Yes, that is correct.
