There are a few threads on this same topic and it sounds like there is a flaw in the TurboTax Business software (downloaded version) with respect to the question asking to check the box if "A member who is not a US-Citizen" is applicable. (this question appears in Business Info > Partner / Member Information" tab. TurboTax should update this Question to "A member who is not a US-Resident" so the form schedule b and k1 forms don’t mistakingly indicate there is a foreign partner when there isn’t.
I received a notice from IRS informing my LLC has a Foreign Partner and I "may" need additional filings. Specifically, it was form CP282. At first I thought an amended return would be needed based on another thread I read on TurboTax community. However after calling the IRS I learned an amended return was not needed or appropriate in this situation. All I needed to do was write “not liable” on the CP282 notice I received and mail it back to the address on the top of the notice. An amended return is only necessary if there is a change in tax liability, which in my case there was not. Below is the link to the information on the IRS website about form CP282 and how to action it.
