Again---you cannot e-file. If you are claiming the childcare credit, your return must be mailed. If your ex amended, that's fine, but his amended return will not be processed for months. Do not try and wait for his amended return.
"......and then pay what is owed then?" What do you mean by that? Does your tax return show that you owe federal tax due? If you have an amount due on line 23 of your tax return, you have to pay by July 15, 2020.
If you have federal tax due you can pay by mailing your payment with the 1040V voucher, having the payment taken out of a designated bank account, or you can pay directly on the IRS website.
