Here you go, the deficit for FY18 was $1.27 trillion, The GDP $19.3 trillion. For the GDP to "cancel" the deficit it would need to end up at $20.57 trillion, just to break even. That is a 6.6% rise in the GDP in one year. Considering that the GDP growth for the first 3 quarters is less than 3% it is doubtful that we will come close to reaching 6.6% for the year.
First of all, your numbers are way off. Second, you are lumping Obama's deficit in with Trump's. That's deceptive, it's the INCREASE we are talking about, and here are the numbers. We've yet to see the full impact of the tax cuts but the increase in the deficit is $222 billion (as of August). GDP does not have to increase by 6.6% to offset that.

My numbers are not off at all.
Using this site from the government...

The total difference between those two numbers is $ 1,271,158,167,127 (other wises known as 1.27 trillion dollars).
That number is the deficit for FY-18. The US GDP for 2017 was $ 19,390,600,000,000. In order to "cancel" the GPD would need to grow to
$ 20,661,758,167,127, which is a 6.6% growth rate over the 2017 GDP.
The full impact of the tax cuts have been a drop in revenue as compared to the previous year.
Taken from the Monthly Treasury Statement, we find these numbers.

Now, since you are not very good with math, I will do it for you.
The tax cuts went into effect in Jan, so we will compare Jan-Aug for 2017 vs 2018
Between Jan-Aug of 2017 tax revenue was $2,225,400,000,000
Between Jan-Aug of 2018 tax revenue was $2,215,674,000,000
You will notice that 2018 is lower than 2017 by $9,726,000,000
6 out of the 8 months have been smaller in 2018 than 2017. The only reason that it is even that close is that April 2018 saw a record breaking month, but as anyone that makes a good living knows, April is the month that those of us who owe the government more than was withheld during the year, pay the government what is owed. So, the large number in April was due to 2017 taxes, before the tax cuts kicked in.
