State tax filing

On Line U(1) "No" box is checked. My LLC is single member and considered a disregared entity. 

I have already mailed my California tax return and From568 (LLC) with the TurboTax instructions I used on April 7 because I could not get any answer. I was supposed to check Yes on Line U(1) of From568, but I mistakenly checked No and submitted it. Does this need to be amend filed? If so, please let me know when and how to file.

I have e-filed with the IRS, do I need to amend this as well?
