I'm 70 yrs old and have SS income as well as pension income. I also have LLC single owner business income and file schedule C. Am I eligible for SEP IRA contributions? If so, can I make 2020 contributions in 20201 by 4-15-2021? I file jointly with my wife. Can she make 2020 IRA contributions in 2021 by 4-15-2021? Thank you!
