Deductions & credits

Same issue. I have same tax like last year. Remember there is  no change in tax liability.  Just child credit is changing this year. I received 4k last year for 2 kids. So this year I expect other half of 6k to show in 1040 total refund. But TurboTax or generated preview form doesn't show other half. Added 2 dependants correctly and mentioned that i received half of  advance child credit payments. So seriously some issue. Not sure do I need to wait or irs will calculate correctly and send other half of credit.  Any advice?
