I was required to upgrade to a self-employment form and then after entering my 1099 info my refund was reduced by $1000 but I don't think I owe that much. Help?

Depending on how much self-employment income you had it is possible that your refund can get reduced by that much if you didn't make any estimated tax payments during the year.  The self-employment income is subject to your income tax rate and to the self-employment tax rate of 15.3%.
