Retirement tax questions

I was able to use the "override" feature in TT on the social security benefits worksheet to delete the $300 on line 6 so the taxable amount matched the IRS program.  I was worried that TT would not let me efile but it did as everything processed and my tax return has been received by the IRS for processing.  I feel better that only $300 was properly deducted from my adjusted gross income.
