Follow-up to my initial comments:
- I assume you have a "successful transmission" "receipt"
- I would still recommend you check your state filing requirements as noted previously
- Assume the fax number you removed agrees with the Form 2553 instructions on page 3 of the attached link https://www.irs.gov/pub/irs-pdf/i2553.pdf
*A reminder that posts in a forum such as this do not constitute tax advice.
Also keep in mind the date of replies, as tax law changes.
