This year some tax returns are taking much longer than they have in the past. This long processing time does not mean you did anything wrong. The IRS is working on backlogs and both the EIC and Recovery Rebate can add to your processing time. See this about refund timing: Refund Timing.
Where’s My Refund? has the most up to date information available about your refund. The tool is updated daily (usually overnight) so you will just usually need to check once a day.
