Are you trying to increase your contributions to the IRA or withdraw tax free? I'm using that $6000 (actually $12k since we're married) to withdraw additional funds from the IRA up to the amount when I'd be taxed. It's very hard to plan the amount since any increase in IRA withdrawn increases taxes on Social Security. That's why having a FULLY functional turbo tax before 12/31 (or as much as can be estimated) is helpful.
I have created a spreadsheet that does the SS taxable amount for me and I track every cent of income from interest and dividends and pensions.
