My refund

My refund was 1509 I believe an I only got 869.02. I would like to know where th the rest of my money is there was only suppose to be 400 take out for fees that leave 643.98 unaccounted for. So where is the rest of that money. I have been used turbo tax for many years and have no problems so why am I having issues with you now? I would like to have the rest of my money deposited as soon as possible I have earned that money.
