After flashing the Lineage OS, go back to the TWRP home screen, click on Install Zip and find the Gapps zip file. This will bring all the Google apps on your device. Once done with both, clear the cache.

Now reboot your device to the system. The first boot might take some time, however, if it takes more time or if you see a boot loop, then turn off your device again and reboot into recovery mode and also wipe the Internal storage + cache + data partition.
