After you file

I'm going to bump off this. 

 

I already filed and 99.9% of the time I am very careful and triple check my return before filing but this year i made a mistake. 

On my childcare expense  the from from the daycare state 4372.00 but for some dumb reason I put 4732.00 accidentally switching the 3 and the 7 making the amount higher. 

Now I calculated it out already and it did not make a change to the over all amount I get back due to the childcare tax credit however it was pure calculation going off the IRS's amounts on their website. 

 

So A is there a way I can go back into my return on turbo tax and plug in the correct number and see if that makes a difference.. 

 

B  What will the IRS do? Will they notice and correct? Will they put my review under return or send the refund as normal so I can amend it right away?
