What form to file? Washington DC, Non resident, Single Member LLC with 80% of gross income from professional services

Hi TurboTax community,

I own a single member LLC registered in California, and I have a client whose billing address, that I invoice, is in Washington D.C., though it's a large corporation and has locations in a number of other places.

I'm trying to figure out:

1. Will I need to file any tax returns to Washington D.C. for 2023? Forms D-40 and D-30 seem to say I do not need to file them
2. Will I have any tax liability to Washington D.C. in 2023?
3. Do I need to make any estimated tax payments?

TurboTax hasn't been helpful because it doesn't generate any forms once I declare that I'm not a resident of D.C.

Here are a few additional details:

• I am not a resident of DC and will not be in 2023
• >80% of my gross income comes from services rendered by me
• I provide professional consulting services
• All of the income is from tax year 2023
• The income is >$12,000
• My client engages in interstate commerce and so do I in the course of working with them

The D-30 booklet seems to show that I'm exempt from filing D-30 because my business is a trade where, "more than 80 percent of its gross income is derived from personal services actually rendered by owners or members of the business"

The D-40 booklet seems to show that I do not need to file form D-40 because I was not a resident. Neither the D-20 or D-65 forms seem correct for my situation either.

Is there something I'm missing here? It seems to me like there is no form for me to file and that I will not have a tax liability to D.C. I just want to make sure I'm estimating my taxes correctly. Any help appreciated!
