Be truthful.  Its well after March 4th and I have not received them. Next I will be using someone else for taxes

It doesn't matter who you use to file your taxes, you won't get them any faster than the IRS can process them.

Please understand that the IRS is deluged.  Lots of folks who normally don't file returns are doing so now because of the stimulus, which adds to the IRS workload.  There were late 2020 tax law changes, and many 2019 returns still to process due to the months-long COVID shutdown.

Going forward, you can change your withholding so that you do not have to wait for a refund at tax.  Why give the govt a tax free loan all year?
