I can't find my return for last year, but I need to enter the amounts in my return for this year. Is there a place that I can find the information?

Where did you file it? If you want to get a copy from the IRS, you will have to pay a fee for that, go to http://www.irs.gov/individuals/article/0,,id=110571,00.html or
Copy of Past Tax Return (http://www.taxdocuments.com/tax_return_copy/)

Actually you can get a free transcript of last year's return. See:
