The IRS website says: https://www.irs.gov/forms-pubs/about-form-1040x
Electronic Filing Now Available for Form 1040-X
You can now file Form 1040-X electronically with tax filing software to amend 2019 or later Forms 1040 and 1040-SR, and 2021 or later Forms 1040-NR. For more details, see our June 2022 news release on this topic.
Nowhere in that June 2022 news release does it say professional tax preparers - only tax payers.
