The easiest way to clear the error is to open the pension splitting optimizer. Only the proper amounts will be applied if you use a figure that's listed as an eligible split amount from the optimizer.
If you're using the Forms method, click the Tools option near the top of your screen and from the optimizer choices, pick the pension splitting optimizer.
If you're using the Easy Step method, use the Find button in the upper right to search/select Split Pension to open the optimizer.
