How can you check your tax refund status if i can't remember how much my exact refund was?

If you used a tax service, you can usually call them and they will have your records. If you used a tax software on your own computer, it should also be in those records. If you did them by hand on your own, I'm not sure how. Look through you're own records. I suppose it may be possible to contact the IRS and ask them.
