What happened to the step in which TurboTax offers to reduce taxes by depositing to a Traditional IRA?

I am an expatriate living abroad. As such, my annual tax filing has changed to:

  1. Take either FEIE or FTC
  2. Use the automatic 2-month extension (In the country where I live and work, I only get the required forms after April 15).

TurboTax has been very helpful in navigating through the maze of forms and calculation, but I just realized that one of the important steps that used be present whenever I owe taxes (i.e. not entitled for a refund) is no longer presented to me: Deposit to Traditional IRA.

 

Back then, when I lived and worked in the US, I could reduce owed taxes significantly by depositing some amount into a Traditional IRA account. If I forgot about it, TurboTax would intelligently present a page/step in which I can take care of that.

 

  But now, when taking FTC, owing a certain amount to the IRS, this step/page is no longer present.

 

Why is that?

Is it because I am filing after April 15th, thus missing the deadline for deposit?

Or is it because I am taking FTC?

Or something else?
