I'm self employed for two months of 2018 Jan-Feb then from March I start a full time (W2) job. I paid my estimated taxes, how would i file my tax return for 2018 in 2019?

What is confusing me, that after paying my estimated taxes for those two months of 2018, I start a W2 job. Now in 2019 when i file my tax return for entire 2018, how do i mention it. Should i just use my W2 since I have already paid my tax for self employment?

what package of Turbo-tax would be suitable for me.
