A 48-hour hold for identity purposes is an internal TurboTax maneuver to give you a chance to contest it if it was not you filing the return. After that first 48 hours (if uncontested), TurboTax then allows the efile to go to the IRS, where it then starts the usual process that can take 24-48 hours after the IRS receives it before the IRS indicates acceptance or rejection. Once the IRS receives the efiled return, it can sometimes be sooner than 24 hours and sometimes longer than 48.
If you filed on 1/29/22, then your 48-hour hold at TurboTax should be up today 1/31/22. And it should go on to the IRS today, where it should in most cases be accepted/rejected in the next 24-48 hours (or possibly sooner or later). Until accepted/rejected by the IRS, the efile status in your TurboTax account should show as "pending".
