Starting an Amended return and original numbers do not look right

I started an amended return and before entering anything, it is showing a Federal Refund of around $1,300 whereas it should show 0. When looking at the original numbers vs. the amended numbers, it shows items that do not correspond to my return even though it includes the actual original 1040 which does have the correct numbers. In column A of 1040-X, it says "Original amount reported or as previously adjusted (see instructions)". I am not aware of any change or why this would happen. How can I determine the reason for this odd change? Is this a bug in TT or should I contact the IRS about this?
