Self employed

However, during my registration attempt, I encountered several options to choose from (see attached). It seems the account dose not accept my business type to register.
Also,
The "Who Can Use This" section of the webpage states, "Single-member limited liability companies (SMLLCs) reporting business income on Form 1040, Schedule C, currently do not have access to a business tax account."

Should I contact the IRS to confirm my business registration? If so, could you provide the appropriate contact number? Any advice on how to proceed?
