I'm doing my S Corp taxes previously done by a CPA. My income and losses are too high compared to previous years. What am I missing?

TT doesn't offer support for those doing corporate returns so print off a copy of both tax years and compare them  and also review your bookkeeping records against the 1120-S to make sure you entered then correctly  AND  the figures will be different from year to year and that is perfectly normal. 

if you imported from quickbooks make sure the accounting method used was the same as last year.
