I would say its OK. My line runs out from the house about 12' then turns 90 deg. then goes 5' and into the tank. Once in the tank it has another 90 and down spout of 2'. I'm no expert nor did I install mine but its been that way for the past 30 years. Just be sure the entire line slopes to the tank.

OK, I had to read that about 6 times to parse it out, but I gather you need to make a turn for some reason. Solids don't like 90 degree turns even it water doesn't mind. It would be better to use two 45 degree elbows with a short straight piece between them if you have the room for that.
Another option would be a wider radius 'sweep' elbow.

yes i would use a long sweep 90 have to turn direction at tank right away will put clean out about 4 feet from 90 to have access
No, previous post was right. Two 45s with a short section between, clean outs every 50 feet. Reason being, most snakes only reach 50 feet and most snakes hate 90s. Make sure there is a tee at the tank outlet too, makes it harder for solids to float into the drain field.
Can be as short as you want, 5-6”. We usually do it according to trench layout and use 1 foot on up.

Use 45 if you have room. Objects can hang up in a 90
