Pension splitting as a deemed resident

TurboTax will not allow my wife to split her pension.  We are both Deemed Residents (I'm a Canadian Armed Forces member posted outside Canada) and the CRA Income Tax  and Benefit Guide for Non-Residents and Deemed Residents states:

Pension income splitting

You may be able to make a joint election with your spouse or common-law partner to split the payments that you reported on line 11500 of your return if you and your spouse or common-law partner were:

• deemed residents of Canada on December 31, 2022 (or residents of Canada on the date of death)

However, TurboTax lists the "Maximum amount of pension that can be split with your spouse" as $0.00.  I'm assuming this is because I selected "Non-resident" (instead of a province) during the Introduction section of Easy Step.  How can I override this to make an election?
