Hello Vanessa A, Thank you so much for your response. I tried adding the ACH explanation and form 8962 (Premium Tax Credit). but the return was still rejected. The client still insists that no one on the return received any ACH benefits or the form 1095-A in 2025. I guess the only alternative left is to manually file the return. Do you agree? If so, do you know the IRS mailing address for a Marlyand resident?
