The IRS will generally notify you within eight weeks of receiving your FAXed response. Times are typically slower this year; much of the staff is still working remotely.
According to the IRS's Understanding Your Letter 12C page,
When we receive the requested information, we’ll use it to process your original tax return. If you’re due a refund, we’ll send it about 6-8 weeks after we receive your response.
Form 8962 is required when someone on your tax return had health insurance in 2020 through Healthcare.gov (or a state marketplace), and took the Advance Premium Tax Credit to lower their monthly premium.
