We have run into the same thing, HR Block still does not support form 7203 in their 2023 Premium and Business software. The 7203 is required for us this year so we obtained the form from the IRS website and completed it. However... 1) it can't be uploaded in the e-file with our return due to HR Block not supporting it, 2) HRBlock does not support uploading .PDF attachments, 3) visited an HR Block office they hadn't heard of 7203 but after researching they confirmed the HR Block consumer software doesn't support it 4) IRS.gov still doesn't support uploading attachments. For such an important form that IRS will hold up processing, it's ridiculous that we have no way to transmit it. Only option left is to mail it to the IRS but we know from past experience that will be futile. We mailed a return 2 years ago, IRS cashed the check right away, then a year later sent us a letter reporting that our return was delinquent (they lost it internally). Very low % chance they'll be able to pair a mailed in 7203 form to the e-filed return. Any other ideas?
