I receive a letter from the IRS they are disallowing part of my tax refund they are only allowing $1,186 so do this mean that this is all I would receive, that amount? And how long will it take to get the money
I can't answer your question without also reviewing the letter you refer to. In general, however, a letter such as this should mean that you will be getting part of the refund you claimed on your return. A month or two after you receive the letter should be the time range for receiving the refund.
