@petergrosse We already answer your question in another thread. Here is the answer we gave you:
In some situations, splitting pension income is not always recommended. When you split your eligible pension income, it will reduce your income and your taxes.
For your spouse, it's reversed situation. It will increase their income/taxes and, sometimes, may impact certain tax credits/benefits they may be eligible for.
If you are experiencing issue with split pension, we will need you to clarify.
Thank you for choosing TurboTax.
