In Quicken, what kind of changes did you make to the old account? - Mark it closed using Tools / Manage Hidden Accounts? - Mark it hidden? - Mark it as "Separate Account"? - Deleted it, together with all its transactions?
OK, thanks. Please go into the Budgets view (Planning tab) and select Budget Actions / Select accounts. Make sure the account is still selected to be part of the budget. AFAIK, accounts marked closed in Quicken should not be automatically deselected from the budget.
And what account did the paycheck transfer go to? Was it to a retirement account? If so, is that retirement account selected as "Transfer out / To [retirement account name]" in the budget view's categories?
