If you turned age 70.5 in 2019, you do not qualify to contribute to a Traditional IRA. The age limit was removed for tax year 2020, but that does not affect your 2019 tax return.

You spouse may be eligible to contribute to her own Traditional IRA under the "Spousal IRA" rules (based on your job income). But it must be in her name.
