Is it true that they are holding off on tax garnishments for student loans?

Yes, but...

UPDATED: On March 25, 2020, ED announced that my federal tax refund would not be withheld to repay my defaulted federal student loan debt. My refund has already been taken. Will I get it back?

Yes, but only if your federal tax refund was in the process of being withheld—on or after March 13, 2020, and before Sept. 30, 2020—for the repayment of a defaulted federal student loan. Your federal tax refund will not be returned to you if the process to withhold your refund was completed before March 13, 2020.

If you have questions about whether your federal tax refund was withheld, call ED’s Default Resolution Group at 1-800-621-3115 (TTY for the deaf or hearing-impaired 1-877-825-9923).
