You must have the IRA custodian make the contribution to your IRA. The administrator must report it to the IRS. Ask the account administrator for the methods you can use.
It does not matter where the money comes form as long as you have sufficient taxable compensation (money that you worked for) on your tax return.
The maximum IRA contributions for 2020 is $6,000, or $7,000 if you’re age 50 or older by the end of the year; or your taxable compensation for the year which ever is less.
(Taxable compensation is generally wages that you worked for - W-2 or net self-employed income minus the deductible part of the SE tax, but can include commissions, certain alimony and separate maintenance, and nontaxable combat pay ).
