Hi, eltigrenoir99-ya.
Let me share some insights about the process of ACH deposits.
Generally, credit card payment deposits take 1-2 business days. Bank transfer (ACH) payment deposits can take 2-7 business days. If this it's your 1st ACH deposit its takes a bit longer while they set your merchant account. It may take 5 business days to receive your first deposit after you take your first successful payment.
For more information, you can check out and read through our article: QuickBooks Payments Deposits FAQ. It helps you learn about how payment deposits work in QuickBooks Online
