After you file

When it says “your tax return is being processed” opposed to “your tax return is STILL processing” it’s a normal status, and so far your on the right track in the processing system. If it changes to STILL processing, then your return might of hit a snag, and might be under review. But March 16th was very recent, I’m sure, it’s “so far, so good! Just continue checking your status on irs.gov at least once a day (their system only updates once daily, usually over night) and from past experience and others who’ve also experienced delays, have reason to believe that calling the irs will only prolong your refund date, once your taxes go under review. However that’s not 100% certain. Only personal opinion. Thanks, and hope all turns out well, in your favor this tax season.
