No Disk space after deleting 200GB using Catalina 10.15.4

HI,

I tried a number of different suggestions to make Catalina 'see' the 200GB free on my MacBook Pro 2017, 500GB HD. I was going to make a back up and wipe off the Disk, however the Time Machine doesn't seem to work (I tried three different external drives, both ASFP and Mac Extended Journaled. When I try to 'backup now' I keep getting the message "... no local snapshots to backup ....". However, I could see the local snapshot in the Terminal. Then, I erased them one by one, turned 'on' "backup automatically" and some snapshots started being created but when tried to do a backup I got the same message "... no local snapshots to backup ...."

My Disk is running full continuously although I erased nearly 200GB (user data) manually. I cannot update to Catalina 10.15.5 as "there is no space" on the HD.

I am getting very desperate and any help is much appreciated. Thank you, MiroslavCatalin

Do you have an SSD in that Mac or a HDD like you indicated? I don't think they sold them with HDD's.

An SSD cannot immediately write to the space that was deleted. The garbage collection routine must prepare the bits for writing. If you have little space left, it may take a while to ready the drive for writing to the previously used space. Keep it on and let it make the storage space ready.

A Time Machine backup drive must be Mac OS Extended (Journaled).

I can't find it now, but there is at least one other post on the"no local snapshots to backup" problem. I can't remember what they did.
