I did my taxes in early January and was accepted by IRS on January 21st. Then when I checked my refund status it states the IRS approved my return on January 29th with a Feb 11 estimated deposit. Well for the past 2 weeks when I check my return status it states it is stll being processed. My son and daughter did their taxes after mine and they are getting theirs on Wed. February 26th. What is holding mine up?
