Its been almost 3 weeks since I filed and when I check the IRS tracker it still says it's processing. Does it usually take this long for a $1200 return?

Generally, a refund is processed within 3 weeks if the taxpayer e-filed. However, each return is different and processing times may vary. For more information about federal refunds, please see here: https://www.irs.gov/refunds/tax-season-refund-frequently-asked-questions
