Long boot time, /etc/initramfs-tools/conf.d/resume not found

After I mount a hdd I am finding relatively long boot time on ubuntu 20.04.On my PCI gen4 nvme, systemd-analyze

Startup finished in 10.499s (firmware) + 3.259s (loader) + 4.428s (kernel) + 8.384s (userspace) = 26.572s graphical.target reached after 8.379s in userspace

which sometimes goes above 31s!

My /etc/fstab looks like this.

# /etc/fstab: static file system information.## Use 'blkid' to print the universally unique identifier for a# device; this may be used with UUID= as a more robust way to name devices# that works even if disks are added and removed. See fstab(5).## <file system> <mount point>   <type>  <options>       <dump>  <pass># / was on /dev/nvme0n1p2 during installationUUID=db3bac2a-f735-4b0d-a6b4-dc99fdf1a60b /               ext4    errors=remount-ro 0       1# /boot/efi was on /dev/nvme0n1p1 during installationUUID=F40C-278D  /boot/efi       vfat    umask=0077      0       1/swapfile                                 none            swap    sw              0       0###/dev/sda1    /work    ext4    defaults    0    1UUID=531b1b74-891f-4f18-a288-cba9990bd31d /work ext4    defaults    0    0

However following Slow boot, long kernel load time, due to wrong resume deviceI tried to edit /etc/initramfs-tools/conf.d/resume which I could not find. When I created a file and followed rest of the advices, nothing improved.

I am completely confused to see conflicting information in various forums. Can anyone please help?

Edit 1: Random Information: sudo blkid | grep swap gave me no output!

sudo blkid0 gives the following output
