Pension Plan - Rollover

A company I used to work for provided me with an option to roll funds from their plan into another plan. I chose to do so because I could no longer contribute to it. Upon entering the rollover value from Form 1099-R, my taxes owed increased significantly. I believe I did something wrong but cannot determine what it was. I have a 5498 IRA Contribution form which show a rollover contribution. Where would I check to confirm I've entered the information correctly?

 

Thank you,

Anthony
