Estimated tax payments are suggested, not required, based on the information provided for the current tax year. In other words, based on the information you input for 2009, TurboTax is suggesting that you make estimated payments for 2010. Since your situation will be different for 2010, you are not required to make those estimated payments.
You can adjust your payments throughout the year. So, if it looks like the withholding from his new job is going to be sufficient, you do not need to make any payments. But, if it looks like you are going to be short, you can go ahead and make a payment. It does not have to be $11,000 per quarter and not each quarter has to be the same. You could do $0 for the first quarter, $0 for the second quarter and then $3,000 for the third quarter. It just depends on what your tax situation is each quarter.
