"revise" ? Did you e-file without those papers? If you did then you have to file an amended return after the return has been fully processed.
If you just stopped working on your return until you found your papers then open the return up by clicking Add a State--you do not really have to add a state, but that gets you back in to add information to the return.
To enter your retirement income, Go to Federal> Wages and Income>Retirement Plans and Social Security>IRA 401 k) Pension Plan Withdrawals to enter your 1099R.
You do not say what other kinds of 1099's you need to enter--there are about two dozen kinds. So if you cannot find the right spot in Federal>Income to enter them, please post back with the specific kind you need to enter.
