No, the 2019 tax return is not still processing because the 2018 tax return has not been filed. The IRS was affected by the pandemic just like any other business. Very few tax returns are being processed until the IRS workers come back on the job. The IRS is not even processing paper tax returns at this time. They are accepting the paper tax returns but they will not be processed until later in the year.
