Adding the additional amount from the 2nd SSA-1099 form does not change tax due, which is still zero. The only change on Form 1040A is Social Security Benefits (line 14a). Taxable Social Security (line 14b) is still zero. Amount of Tax Owed (Line 50) is still zero.
No, you are not required to file an amendment if the change does not affect your federal or state tax liability. You can go ahead and file the amendment anyway, to avoid possible questions from the government about the missing SSA-1099. For the cost of a postage stamp, it's better to be safe than sorry.
