Enter your current actual balance (what your bank/card shows) and set the date to today. Scheduled payments before that date are treated as already included — only items after it get reconciled. To fix a balance later (e.g. a bill came in different to forecast), just edit it here and set the date to today.
Only this one instance moves — the regular schedule and every future payment stay exactly where they are.
