Hi There, How can I amend tax return for year 2020 that I've filled already? This is for unemployment assistance (tax-free for $10200) and child support: Thanks

The agreement would also make the first $10,200 worth of benefits payments tax-free for households with annual incomes less than $150,000.
The legislation would provide $3,600 per child under the age of six and $3,000 per child age six through 17 for a single year.
