Why am I being asked to "fix" form 2210 by checking the box allowing the IRS to figure the penalty when I chose to pay the penalty from my refund?

As state by HelenC12 Employee Tax Expert:

Form 2210 has not been finalized. . We are waiting for the IRS to finalize and give us the approval to update our software. Please revisit TurboTax at a later time. 

Even if you didn't pay estimated income taxes, if you underpay your taxes during the year, you might face an underpayment penalty at tax time. TurboTax automatically calculates this amount.

• Taxes are pay-as-you-go. This means that you need to pay most of your tax during the year, as you receive income, rather than paying at the end of the year.

In general, you may owe the penalty for 2019 if the total of your withholding and timely estimated tax payments didn't equal at least the smaller of:

1. 90% of your 2019 tax, or
2. 100% of your 2018 tax. Your 2018 tax return must cover a 12-month period.

Tip: To reduce or possibly even eliminate your underpayment penalty,  search for annualizing your tax (use this exact phrase) inside TurboTax. This will take you to the underpayment penalty section and we'll take you through the steps to possibly reduce your underpayment penalty. (If you don’t see Jump to annualizing your tax in the search results, make sure you’re in your return and not on the Tax Home page.).
