1541 is an an internal code that the IRS uses to identify returns that have been "Delayed". This doesn't mean there is something wrong with your return, it could simply be that the IRS has an overflow of returns at this time and is behind schedule on issuing refunds. There are different reasons accounting for the 1541 reference number.
To be absolutely sure on the status of your refund, I would recommend to contact the IRS directly mention the reference the code 1541 to them. You can reach them at +1(800) 829-1040. Check Where's My Refund? as well tor tracking the refund. The IRS website updates every 24 hours, so I would keep checking it for an update.
If the below applies to you, this could likely be the reason:
If you claimed an Earned Income Tax Credit and/or an Additional Child Tax Credit and filed before February 15, 2019, you’ll get your refund the week of February 27 at the earliest. The IRS states they will begin issuing tax refunds on returns with the EIC or Additional Child Tax Credit on February 27, 2019.
According to the IRS on taxpayers claiming Earned Income Tax Credit or the Additional Child Tax Credit- https://www.irs.gov/pub/irs-pdf/p2043en.pdf
Claiming the Earned Income Tax Credit or the Additional Child Tax Credit
If a taxpayer is claiming the EITC or the ACTC, they can file
their return any time after the filing season begins. However,
by law, the IRS cannot issue refunds before mid-February for
tax returns that claim the Earned Income Tax Credit (EITC) or
the Additional Child Tax Credit (ACTC). Keep in mind that only
a small percentage of total filers will fall into this situation.
While the IRS will process taxpayer returns when they are
received, it cannot issue related refunds before mid-February.
The IRS expects the earliest EITC/ACTC related refunds to be
available in taxpayer bank accounts or on debit cards starting
on Feb 27, 2019, if they chose direct deposit and there are no
other issues with their tax return.
