Thank you for giving me the opportunity to assist you. I will give the best answer that I can with the information provided.
Most likely if your wife is receiving a pension from a decedent, you should be receiving form 1099R. The amounts for the taxable portion of the pension should go from this form onto line 15b (for IRA) or 16b (pension) of your 2009 1040.
Please let me know if you need additional assistance..
