My wife works part time and she files taxes jointly with her dad. So, I think, My wife files her own I-864 and her dad files only I-864A since they file taxes together?

My wife is citizen of United states and petitioning for my permanent residence by filling i-130 out. At the same time I am filling i-485. One of tthe requirement is filing i-864 which is affidavit of support. In my case my wife does not earn enough to sponsor me so we have her dad as joint sponsor. I am little confused regarding which forms to fill out since, I read on USCIS website that if theres joint sposnor then joint sponsor also have to submit I-864A.

1) Petitioner and joint sponsor fills separte i-864 and joint sponsor fills additional I-864A? OR

2)Petitioner fills I-864 and joint sponsor fills I-864A? OR

3) Petitioner and joint sponsor fills separtae I-864 with no need of I-864A?

Please help me, what should I do in my case? Thanks
