Yes, you can contribute to all plans if your income is within the threshold limits. Since your MAGI is less than $196,000, you could make a spousal traditional IRA contribution for the full $7000 and deduct it on your 2020 taxes if made by 4/15/21.

You both would be eligible for Roth IRA contribution up to $7000 since your MAGI is less than $196,000. Note the deadline for 2020 IRA contribution is 4/15/21.
