Typo Mistake {Mathematical Error}

[swaila2]

I made a typo mistake when entering advanced child tax credit on my e file. Instead of $1,500 I entered $1,250. Will IRS correct this error automatically? It has already been accepted by IRS so I wanted to find out if this minor error will affect me. 

 Also, will that delay the approval of my return? Will they have to write to me before approving and issue my refund?

The IRS will check and find your  mistake but you can expect a delay in processing your refund.  Do not expect a quick refund.

Will the IRS see this a minor mistake or serious one.

@swaila2 Millions of people made mistakes with the stimulus money last year and their refunds were delayed.   The child tax credit advance payments are new this tax year and there are going to be plenty of mistakes made.   Lots of people are very confused and they are making mistakes.    The IRS will find the mistakes and correct them but it will add to the processing time for the already backlogged and understaffed IRS.
