refund I entered all of my information and my total tax withheld is about 34k but turbo tax says I should get a refund of 54k why?

Depending on other aspects of your return, you may be receiving a refundable tax credit that has increased your refund over and above your withholding amount. 

However, just to be on the safe side, you should take a look at your actual tax return as compared to your documents that show withholding and be sure that the total of all of your withholding matches the amount reported on line 25d of your Form 1040.  If the numbers are different, there may be an input error somewhere.  

You can use Forms Mode to see your Form 1040 if you are using a CD/downloaded version of TurboTax.  Or, if you are using TurboTax Online, see the steps below.
