Line 40 of Form 1040A is your combined tax withholding reported on Forms W-2 and Forms 1099-R.  The IRS is asking you to provide copies of those forms, perhaps because amounts you entered into TurboTax from these forms do not agree with the information on these forms sent directly to the IRS by the payers.  This suggests that either you made an error when entering these forms into TurboTax or one of the payers failed to file the required copies with the IRS.
