Taxes letter from irs

[Benemma1023]

So I received a letter from irs that they are viewing my accuracy on my taxes and below states that they are looking into income, tax credits, income withholding and business, I don't have a business, I reviewed my return multiple times and just now again and do not see any errors under any of this, it just says to wait up to 60 day before they may send it, I've never had this happen before. But the return was accepted just hours after submitting it.

You may have been randomly selected for review or they may have something in their system saying that you are missing a document, like a 1099 or a W-2 or something.  The only thing to do at this point is wait and see what they find IF ANYTHING.  They may look and see nothing.  

You can also enter your letter number in the Taxpayer Advocate Services to find out more about it or see if you need to take additional action.

Where do I find the number to enter in

The IRS letter number should be in the top right corner.  It might say something like LTR 0096C or CP 12 etc.

Sorry but I think that is a standerd form letter.  I would say you have randomly been selected for audit. Your Return does not have to be an error, as the selection is random.

[Benemma1023]

It can't be an audit yet, just a review is exactly what it states, but when I look up the letter number, there is a map of possibilities that it could be and when I found my letter number I needed on the paper it says 0 results and I can't find it on that map.

What is your letter number?

So only thing that may be flagged is i filed married separately because me and my husband split last year, and my income was significantly lower, as he made more, but we agreed I claim the kids and have been very civil about it and he hasn't filed yet either because i usually do them for him as well. Could this be why

[Benemma1023]

Says it 4464c and I can't find it
