Notice CP282 for erroneously putting a partner as a "foreign partner" on Form 1065.

Situation: I e-filed my partnership's Form 1065 with TurboTax Business, which has been accepted by the IRS. I subsequently received a Notice CP282. That notice says that I may have additional filling requirements for having a foreign partner.

 

My Filing Error: My partner is a US resident/green card holder. The internet research that I have done indicates that I should have listed her as a "domestic partner" instead of a "foreign partner" on Form 1065 Schedule K-1, Line H-1.  All of the numbers are accurate on the original filing. The only error was that I listed her as a "foreign partner".

 

How do I fix this?:  I am a novice so suggestions are greatly appreciated. I think that I have two steps to fix this.

 

1. Reply to Notice CP282. Write "not liable" across the top of the notice and mail it back to the address on notice. Reference: https://www.irs.gov/individuals/understanding-[product key removed]e?utm_source=OTC&utm_medium=Mail&...

 

2. File either a superseded or amended Form 1065, marking the partner as a "domestic partner".

 

Superseded. There is one month until the filing deadline, which makes me think a superseded filing is the correct fix. However, I cannot find a lot of information on filling a superseded Form 1065 and that worries me. Can I print out a corrected Form 1065 with attached Schedules, write "superseded" across the top and mail it in to replace the erroneous original filing? Where do I mail it? I e-filed the original.

 

Amended. Since the original Form 1065 has already been accepted, must I amend the filing with Form 1065X and attached Schedules? Must I wait until after the filing deadline to do this?

 

*For the correspondence I will use certified mail with receipt requested.

 

All help is greatly appreciated!
