Get your taxes done using TurboTax

Is it the excess accumulation penalty for not taking enough RMD from all of your accounts?  That is currently a problem they are working to fix.

 

Or the underpayment penalty on 1040 line 38?

You might be able to eliminate it or at least reduce it.  You can go to Federal Taxes tab or Personal tab, under Other Tax Situations and select Start by the Underpayment Penalties. You will answer a series of questions that may reduce or eliminate the penalty. Or you can elect to have the IRS figure the penalty for you.  It's form 2210.

 

It's under
